Ummm no. Skidoo had RER in 2002. Polaris had it on there sleds in 2003. Not sure if brp will give this up though. Looks pretty cool. Might be hard to patten though as this isn't new technology, just new to sleds.
RER first came out on the 250 single tundras in 1997- 98ish.
I heard that Doo gave poo permission to use RER as part of a settlement for a lawsuit citing patent infringement on front suspensions of the s- chassis sleds.
Maybe Poo can get the shot by claiming Doo copied their flick ability and instantaneous lift.
